Running an LED in Reverse Could Cool Future Computers

Researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small space that current methods can’t remove heat quickly enough.

This could turn out to be important for future smartphones and other computers. With more computing power in smaller and smaller devices, removing the heat from the microprocessor is beginning to limit how much power can be squeezed into a given space.

  I have an idea!

  As a way of removing heat from a microprocessor, how about we remove transistors from a microprocessor! x86 must DIE DIE DIE !!!

  No need to support old 8 and 16 bit instructions with segment registers and ability to boot DOS 1.0. Forty years of legacy baggage is time to go away now thank you.

  dude, I have a whole bunch of old x86 dies. I think they are called CPUs.
